You could record a movie as discussed in the <a href="http://www.k-wave.org/documentation/example_ivp_saving_movie_files.php">Saving Movie Files Example</a> (open this in MATLAB to see the code).</p> <p>Alternatively, you could set the sensor mask to cover the whole domain, and then extract the snapshots at the relevant times from the sensor data. Note, there is no way to tell k-Wave just to record the field at specific times, so the sensor data will contain the field at every time step.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/photoacoustic-pressure-distribution-in-complete-domain#post-7591 Thu, 11 Jun 2020 10:26:06 +0000 Mayank 7591@http://www.k-wave.org/forum/ <p>Dear Prof. Brad,</p> <p>I took the following parameters others are fixed accordingly;</p> <p>computational grid = 256*256;<br /> dx = 1e-6;<br /> dy = 1e-6;</p> <p>source or radius = 5*dx; in the center;</p> <p>so my question is, How to plot pressure variation with color bar in the whole computational domain at t =0, 15ns, 30ns, 45ns etc. </p>
